Abstract:
The Marlboro Clay formation is a late Paleocene/early Eocene geologic formation that outcrops in significant portions of Prince Georges County, Maryland with an average thickness of 4.6-9.1 meters. Due to rapid urbanization in this county, the Marlboro Clay formation is of great importance because of its unstable
characteristics including slow permeability, possible high shrink-swell potential, and potential landslide occurrence. These unstable characteristics make this formation unsuitable for most building structures. The objectives of this project were to compare and validate geospatial analysis techniques to map the depth and thickness of the Marlboro Clay formation at a county scale, and to evaluate the mineralogical and physical characteristics of unweathered and pedogenically altered Marlboro Clays.
